I'd like to know how many of these things are being taught to 5th graders today?

Redman, this stuff is probably in the text books, but whether the kids learn is up to each individual. Then again, if we learned it in 5th grade but forgot it by adulthood, then was that time well spent?

one kilowatt hour? Ppprrrrrrr!!!

I wouldn't trust "Are You Smarter Than a 5th Grader?" to get questions like this right. For example, the question "How many watts are used during one kilowatt-hour?" is actually meaningless: there are 1000 WATT-HOURS in a kilowatt-hour, or 1000 watts in a kilowatt, but watts and kilowatt-hours can't be directly compared because they're measuring different things. It's like asking how many miles-per-hour it takes to get from New York to Boston.

The great thing about this is that while the given answer is wrong, it's exactly the sort of answer a fifth grader would give. So, if you are smarter than a fifth grader, you lose.

I know this because I know a lot of math and have studied concepts like dimensional analysis that are usually glossed over. On the other subjects I don't know as much, but I have to assume their track record won't be much better.
